The first time I saw this question, the example was Jaws. If you watch Jaws backwards, it's about a shark that vomits out person after person until they all decide to open a beach.
I am +1 pretty much every post here for any media I've watched (or understand well enough). No, I actually haven't watched Fight Club.
Indiana Jones (in general): a highly respected professor and archaelogist steals valuable treasures and artifacts, then goes to great lengths to hide them in various exotic locales and set up numerous dangerous traps to protect them.
The King's Speech: The king's brother gets a divorce, allowing him to take over the throne by some complicated legal shenanigans. The former king is so flustered that he develops a speech impediment.
Gravity: a woman ascends into space where she meets a hansome middle-aged man. Together, they construct a giant telescope out of clouds of debris orbiting the earth.
Romeo and Juliet: two teens wake up in bed together. Juliet is holding a knife and Romeo's spits out a mouthful of poison. They run away from each other, thoroughly distressed and confused, but they run into each other repeatedly even as they try to get some distance. By the time they forget the whole ordeal, they've ignited a gigantic blood feud between their families.
